The ASUS Vivobook S 15 OLED offers a vibrant OLED display with a higher resolution and refresh rate, making it excellent for visual tasks and smoother motion. It's also more compact and lighter, enhancing portability, and has a sleeker design with a number pad. However, it's pricier and has fewer ports, with only USB-C for charging and no HDMI or Ethernet. Its performance is well-rounded, but the Intel Arc GPU may not match the gaming and 3D capabilities of the Dell's Nvidia MX570. In contrast, the Dell Inspiron 14 5420 provides more RAM for better multitasking and has a wider range of ports, including HDMI and Ethernet, which is convenient for connectivity. The Nvidia GPU gives it an edge in gaming and machine learning tasks. It also has a more robust build quality and better battery life, making it a solid choice for general use and productivity on the go. However, the display, while still good, isn't as impressive as the ASUS's OLED, and the laptop is slightly larger and heavier, which could impact its portability. Ultimately, if you prioritize a superior display, a more compact design, and are willing to pay a bit more for these features, the ASUS Vivobook S 15 OLED is the way to go. On the other hand, if you need more RAM, better gaming and 3D performance, and appreciate a wider selection of ports and longer battery life, the Dell Inspiron 14 5420 is the better choice.

"The Asus Vivobook S 15 OLED excels as a capable work machine at an affordable price. It offers commendable performance, thanks to its 12th Gen Intel chip, delivers quality on-screen entertainment with its 15.6-inch OLED display, and can (kind of) get you through a full day of work. Oh, and its special Asus Antibacterial Guard is a nice touch for those who like a clean laptop."
